enables carriers to provide universal
homogenous Carrier Ethernet service while
saving operational costs.
The device delivers SLA-based business
services to the customer premises over
native Ethernet interfaces, terminating
over any type of packet network.
ETX-203AM transports Ethernet traffic,
ensuring TDM-like performance and Five
Nines reliability.
ETX-203AM can deliver IP VPN, VoIP, and
dedicated Internet access over the same
physical link as a Layer-2 LAN-to-LAN
service, all with differentiated quality of
service and end-to-end monitoring.
The ETX-203AM architecture ensures
powerful traffic management that allows
the service provider to control bandwidth,
monitor and enforce network traffic SLA.
ETX-203AM
Universal Carrier Ethernet Demarcation Device
The ETX-203AM modular uplink design
enables utilizing a single Ethernet
demarcation device over different access
networks and infrastructures, while
providing uniform service. The following
uplink modules are available:
OAM
Featuring ultra fast, hardware-powered
processing, ETX-203AM performs OAM and
PM measurements in line rate with
maximum precision, offering the following
powerful benefits:
·
GbE – Two redundant combo ports
(SFP/copper)
·
·
EFM (Ethernet in the first mile) DSL –
One or two SHDSL ports providing up
to 22 Mbps over bonded SHDSL.bis
copper lines.
Immediate detection of loss of
continuity (LOC), ensuring under 50 ms
protection switching
·
Highly accurate frame loss
measurements of live traffic
·
Flow-level (per CoS) monitoring,
enabling simultaneous processing of
multiple OAM sessions with E-LAN and
E-Tree support
·
Non-disruptive MAC and IP level
loopback testing of network integrity.
MARKET SEGMENTS AND
APPLICATIONS
ETX-203AM is used as an Ethernet
demarcation device that separates the
service provider network, the access
provider network, and the customer
network, providing proactive service
monitoring and easy fault localization
throughout the entire network (see
Figure 1).
ETHERNET
Classification
Traffic is mapped to the Ethernet flows
using very flexible classification criteria
based on incoming port (port-based
all-to-one bundling), VLAN ID, VLAN
priority, IP precedence, DSCP, Ethertype,
and IP/MAC source/destination address.
Classification is defined for both VLAN
tagged as well as untagged traffic.
ETX-203AM provides these types of
Ethernet OAM:
·
Single-segment (link) OAM according
to IEEE 802.3-2005 (formerly 802.3ah)
for remote management and fault
indication, including remote loopback,
dying gasp with SNMP trap, and MIB
parameter retrieval. Active and passive
mode are supported.
Layer-2 Control Processing
The device can be configured to forward
Layer-2 control frames per EVC (including
other vendors’ L2CP frames) across the
network, to peer supported protocols
(IEEE 802.3-2005 and LACP), or to discard
the L2CP frames.
·
End-to-end connectivity OAM based on
IEEE 802.1ag that enables Ethernet
service providers to monitor their
services proactively and guarantee that
customers receive the contracted SLA
·
End-to-end service and performance
monitoring based on ITU-T Y.1731.
Fault monitoring and end-to-end
performance measurement include
delay, delay variation, frame loss and
availability.
Traffic Management/QoS
Different service types require different
levels of QoS to be provided end-to-end.
QoS can be defined per subscriber as well
as per service. QoS has three aspects: rate
limitation, traffic shaping, and traffic
prioritization.
Traffic policing is applied per flow or group
of flows, and operates according to the
dual token bucket mechanism based on
user-configurable CIR + CBS and EIR + EBS.
Traffic can be limited to the line rate or
the data rate.
Forwarding
Every flow per EVC or EVC.cos has its own
queues and scheduler supporting strict
priority and weighted fair queues (WFQ).
Queue blocks of eight queues per EVC are
scheduled and shaped, forming an H-QoS
model with shaped services and prioritized
classes of service. The WRED mechanism is
used for smart packet drop.

Data Sheet
The VLAN priority bit in Ethernet frames
can be modified at network ingress
according to the ‘color’ of the frame. This
allows service consistency and QoS
continuity across color-aware (drop
eligible-enabled) as well as color-unaware
networks.
Smart SFPs
Integrated management of MiRICi smart
SFPs provides TDM (E1/T1/E3/T3/
OC-3/STM-1) connectivity over PDH or
SDH legacy networks. ETX-203AM
supports configuration and statistic
collection for the smart SFP TDM port.
RESILIENCY
Dying Gasp
ETX-203AM reports power failures to
defined network management stations by
sending an IEEE 802.3-2005 message or
SNMP trap, thus enabling the unit to
properly disconnect from the network
with notification of the reason for the
service problem.
Ethernet Path Protection
ETX-203AM applies standard ITU-T G.8031
Ethernet Linear Protection switching for
fast protection of one or more EVCs on an
end-to-end. The standard implementation
ensures interoperability with third-party
devices. With standard APS functionality,
Ethernet OAM messages provide
bandwidth-efficient unidirectional or
bidirectional 1:1 protection.
The EVC protection path can be configured
on the same network port, enabling the
transport network to provide an
alternative path for the working and
protecting path. It can also be configured
on separate network ports, adding
protection at the access layer and
enabling load balancing on network
interfaces by splitting traffic between the
two network ports.
The performance of the hardware-based
Ethernet OAM together with protection
switching for physical layer failure ensures
fast protection in any scenario.
Fault Propagation
The unit provides a user-configurable fault
propagation mechanism in the
network-to-user or user-to-network
direction.
The flow level protection provides a full
set of manual commands for maintenance
purposes.
When a link failure is detected or OAM
failure received, ETX-203AM can shut
down the affected port or forward the
OAM failure message. The fault
propagation mechanism enables routers
and switches connected to both ends of
the link to reroute the traffic to the
redundancy path.
The following security protocols are
provided by ETX-203AM to ensure client
server communication privacy and correct
user authentication:
Link Protection
ETX-203AM provides the following
network interface protection modes:
·
·
802.3ad link aggregation (LAG),
providing 1:1 link protection with Link
Aggregation Control Protocol (LACP)
support
Dual homing (1:1), allowing
ETX-203AM units to be connected to
two different upstream devices.
MANAGEMENT AND SECURITY
Ports
The unit can be managed using the
following ports and applications:
·
Local management via an ASCII
terminal connected to the RS-232 port
·
Out-of-band management via a
dedicated management port.
·
Remote inband management via user
or network ports routed via separate
VLANs, Telnet, or an SNMP-based
management system.
Command Line Interface (CLI)
Databases and scripts of commonly used
commands can be easily created and
applied to multiple units using command
line interface.
Trap Synchronization
Traps are sent with sequence IDs to
network manager groups, to enable the
managers to detect when traps are lost
and request the traps be sent again.
Zero Touch Provisioning
IP address and mask, default gateway, and
software and configuration files can be
automatically obtained using standard
DHCP client functionality. This enables
seamless node setup and configuration
for quick and scalable network setup and
deployment as well as configuration
consistency when nodes must be
replaced.
·
SNMPv3
MONITORING AND DIAGNOSTICS
·
RADIUS (client authentication)
·
TACACS+ (client authentication and
accounting)
·
SSH (secure shell communication
session)
·
SFTP (secure file transfer).
RFC-2544
The device provides a built-in RFC-2544
wirespeed traffic generator and analyzer
for unidirectional and bidirectional testing
of throughput, latency, and frame loss.
Based on standard OAM messages, the
tests can be simultaneously performed
over multiple flows, at the EVC.CoS level.
Enhanced RFC-2544 functionality provides
service-oriented KPI analysis. SLA
conformance is measured per service
bandwidth and packet size, within a
user-defined amount of time, for faster
service introduction.
